Question

If a hydrogen atom in the
excited n = 3 state relaxes to the ground state, what is the
maximum number of possible emission lines? a. 0, b. 1, c. 2,
d. 3, e. infinite.

For a hydrogen atom,
calculate the wavelength of the line in the Lyman series that
results from the transition n = 4 to n = 1. The
Rydberg constant equals -2.18´10-18 J. a. 30.4nm, b. 97.2nm, c.
114nm, d. 121nm, e. 182nm
